You know those genius, almost sentient quadcopters that can learn new skills like juggle balls, fly in tandem, work together, go through hoops, attach themselves to wall and basically do things that will eventually destroy mankind? This guy, Kai Hou, is like the human equivalent of those. He's an acrobatic master that can flip, spin, jump, turn, tumble through the air and do basically anything that shreds our typical sense of gravity. I wish I could jump like him.
